The invention is based on the counter-pulling device on the upright post, has balanced structural stress and high stability, presses the prefabricated part into the foundation through the action of counter-pulling force, has no noise influence, has no impact force during pressurization and has high vertical precision.
Disclosure of Invention
The invention aims to provide a counter-pulling device based on an upright post and a using method thereof. The invention aims to solve the problems, a pressurizing winch and a hoisting winch are started, the horizontal tension of the pressurizing winch is transmitted to an upper counter-pulling frame after being matched through a pulley block transmission between the upper counter-pulling frame and a lower counter-pulling frame, the upper counter-pulling frame is provided with a vertically downward pressure, a force transmission rod is fixed with the upper counter-pulling frame, namely the force transmission rod also obtains a vertically downward pressure, a prefabricated component is sleeved at the bottom end of the force transmission rod, and the prefabricated component is pressed into a foundation under the action of reverse force.
The invention is realized by the following technical modes:
1. a counter-pulling device based on an upright post and a using method thereof are disclosed, wherein the device comprises the upright post, an upper counter-pulling frame, a lower counter-pulling frame, a dowel bar, a hoisting winch and a pressurizing winch. The vertical column is provided with a slide rail, the upper reverse pulling frame is connected with the vertical column through the slide rail, the lower reverse pulling frame is fixed at the bottom of the vertical column, one end of a dowel bar is fixed on the upper reverse pulling frame, the hoisting winch is connected with the upper reverse pulling frame through a steel wire rope, and the pressurizing winch is connected with the lower reverse pulling frame through a steel wire rope. The tension of the pressurized winch gives a vertical downward pressure to the dowel bar through the mechanical transmission between the upper counter-pulling frame and the lower counter-pulling frame.
2. The upper reverse-pulling frame and the lower reverse-pulling frame can be arranged at any angle along the circumferential angle of the upright post.
3. And a plurality of groups of pulleys are uniformly arranged on the upper reverse-pulling frame and the lower reverse-pulling frame, and the pulleys of the upper reverse-pulling frame and the lower reverse-pulling frame can achieve different transmission multiplying powers by winding steel wire ropes.
4. The dowel bar is fixed on the hoop of the upper counter-pulling frame, and the top end of the dowel bar is provided with a connecting flange.
5. The hoisting winch and the pressurizing winch are controlled by a follow-up system.
6. A counter-pulling device based on a stand column and a using method thereof are as follows: the horizontal tension of the pressurization winch is transmitted to the upper counter-pulling frame after being matched through the pulley block transmission between the upper counter-pulling frame and the lower counter-pulling frame, so that the upper counter-pulling frame is provided with a vertically downward pressure.
Compared with the prior art, the invention provides a counter-pulling device based on an upright post and a using method thereof, and the counter-pulling device has the following advantages:
1. the counter-pulling device is based on the design on the stand column, and has simple structure, balanced stress and high stability;
2. the vertical downward pressure is generated, and meanwhile, the noise is avoided, so that the device is used for an area with high noise requirement;
3. the design of the flange plate at the top end of the dowel bar is beneficial to the connection of an external pressure device and provides pressure compensation;
4. the winches are controlled by a servo system, so that the phenomenon of disorder of the steel wire rope can be effectively prevented.
